could result in death or serious injury.
Lights Troubleshooting Guide
Problem Possible Cause Solution
Mast lights off,
checking outside
control box
Light fixture is too hot Allow light to cool 10–15 minutes before restarting.
Loose lighting
connections
Inspect the connections inside the mast junction box and each mast light
housing/socket.
Damaged or loose
electrical cord
Inspect the mast electrical cord for damage and check the cord connections
inside the control box.
Faulty fuel filter With engine running and lights off, measure voltage and frequency at the
GFCI receptacle. Voltage should indicate 120VAC ± 5%, and frequency
should indicate 60.7 Hz ± 5%. If frequency and voltage are both low
(<114VAC, <58 Hz), replace the fuel filter.
Faulty generator
capacitor
Measure the capacitance of the generator capacitor. If measurement is
outside rating (as indicated on the capacitor), replace the capacitor.
Mast lights off,
checking inside
control box
Loose lighting
connections
Inspect the connections inside the control box.
Generator output
incorrect
Check the incoming voltage to the ballast driver by checking the available
voltage on the GFCI receptacle. Incoming voltage should be 120V ± 5V. If
voltage is incorrect, the generator may require service.
